Variable Moving Average Bands [LazyBear]

VMA Bands are ATR bands with VMA as its centre. For a description of options, refer to my VMA post:
I have moved VMA calculation in to a separate function. Feel free to use calc_vma() in your scripts. For more MA calculation function ( KAMA , VIDYA and others), refer to my complete list of indicators below.

Wish you all a very prosperous New year. Hope these indicators make you all more money this year too :)

Very nice, indebted to yours, ucsgears and ChrisMoody's scripts.
Great work, as usual.
Have you used these, or just coding them for fun?

I do use them occasionally to get a different feel, but usually stick to only a few (1 momentum & 1 volume).

Each new indicator teaches me something new about price though, so mostly I code to learn :)
